Engraving letters

[CNCMike]

Hi Guys,

I have run into a problem with machining small letters (1/4" or smaller for example) and would like to know if there is a solution.

 

Is there any way to make the tool follow the center line of the letter rather than the outline? The small letters start to look like bold print or blur together because of this.

 

Thanks for the help, Mike

turn compensation off this will make the tool follow the center of the line

If it's a font with outlines, a rectangle for the letter "I" for example, you'll need to offset the geometry to the center of the letter. Or change to a Stick font if possible.

Like ocean said stick geo. Create letters will give you alot of options on stick lettering. Test it with MCX(Box) Font and it it will not do, there are defaults in the drop down and True font gives you a huge variety of styles and options

 

like preston said , comp off, try window selection it has not failed me yet.

Since the letters are not stick font changing the offset will not fix the problem. I will give stick fonts a try and see if I can get the results I am looking for.

 

Thanks for the help, Mike

Mike we do .06 and .12 high letter all the time and only use Stick for something like this. .003 to .005 is the max depth and may have 60 plus characters in some of the engravings.

1/4=small? thats huge, but stick with stick if you can.

Hi Guys,

I looked into stick letters, but they are just that, stick. I need the letters to be in the correct font style, so they are out of the question in this case.

 

The depths I am using have been 0.001 to 0.003 which seems about right. Is there any specific tool that works well for fine engraving. I am using small ball mills.

 

Jay,

I will take a look at the video and see if it helps.

 

Thanks again, Mike

Mike:

We engrave tire mold with letters 0,15" height.

We make our own tools. For this we use a Carbide rod 1/8". Grind a plane to 1/16" and grind the tip in a certain angle. If you need a picture I can send it to you.

We make our own letters and create the sepecific .DAT file. There is a recently topic about this.

For machinig you will need ver high speed.

In standard machines we use a multiplier and the tool runs to 25000 rpm.

Now we have an engraving machine that works to 50000 rpm.

We use simple 1/8" 90 degree chamfer tool single flute hhs for alum.carbide for steel it works well.

we use small #1 or #2 centerdrills for engraving, they work very well and last a long time. As for font we use stick and turn comp to off.

Hey Mike ,

Don't use "letter"

JQLuong :

 

You have it already;

Go to create/drafting/create note/properties and you will be able to select from several fonts to use including stick.

We buy split-end engraving tools from Micro100. They work great!
